When an alternate airport is required by operating rules, which statement is NOT a requirement?

• A. The alternate aerodrome must be served by an approach based on other than GPS navigation.
• B. The airplane must have operational equipment capable of using that navigational aid.
• C. The required navigation aid must be operational.
• D. The alternate aerodrome must have an ILS approach.

Answer: (D)

When selecting an alternate, you must ensure there is an instrument approach published for that airport that you can actually fly with your aircraft’s navigation equipment, and that the navigation aid used for that approach is operational. You don’t have to have the airport with an ILS approach specifically; GPS-based (RNAV) or other non-ILS approaches are acceptable as long as they are published and usable with the aircraft’s equipment. So the statement that the alternate must have an ILS approach is not a requirement.
